Cystic papillary carcinoma has a low mitotic activity, which results in a more indolent course and a good prognosis. However, invasive micropapillary ductal carcinoma has a more aggressive phenotype, even though approximately 70% of cases are ER-positive. A retrospective review of 1400 cases of invasive carcinoma identified 83 cases (6%) with at least one component of invasive micropapillary ductal carcinoma. [77]

Additionally, lymph node metastasis is frequently seen in this subtype (incidence, 70-90%), and the number of lymph nodes involved appears to correlate with survival.
